In a post-apocalyptic future, thousands of special operatives are tasked with preventing the collapse of society. These operatives, known as "travelers", have their consciousnesses sent back in time and transferred into the "host" body of present-day individuals who would otherwise be moments from death, to minimize unexpected impact on the time line. The transfer requires the exact location of the target, made possible by twenty-first century smart phones and GPS providing time, elevation, latitude, and longitude (TELL) coordinates that are archived for use in the future. Trained using social media and public records concerning their hosts, each traveler must maintain the host's pre-existing life as cover for the rest of their lives, while carrying out missions in teams of five. These missions are dictated by the Director in the future who monitors the time line, and are aimed at saving the world from a series of catastrophic events. One method by which the Director communicates with travelers is via pre-pubescent children used as messengers; unlike adults, any child can safely be taken over for a few minutes by the Director and then released from control without risk of killing them. All travelers are required to behave according to certain protocols to protect the time line:

Marcy puts herself in a near-death state to recover her lost memories from when she was reset. The memories she receives include those of the original host Marcy, showing that the host's intellectual disability was caused by Vincent/001 testing Simon's incomplete consciousness transfer technology on her. While she is out of commission, Mac and the rest of the team are ordered to provide Hall with backup in protecting the future 53rd President of the United States, who is currently a prepubescent girl.

U.S. travelers have historically overlooked Mauritius in favor of other Indian Ocean destinations like the Seychelles and Maldives. That could all change, though, now that this remote, idyllic island some 1,200 miles off the African coast has become easier to reach. A flurry of new airline services launched at the end of 2017: KLM began servicing Mauritius from Amsterdam, and British carrier Thomas Cook Airlines introduced biweekly flights in November. Upon arrival, travelers can take in dreamy lagoon views from the newly reopened One&Only Le Saint Géran, fresh off a multimillion-dollar renovation. Every room and suite now has a private terrace or balcony, marble baths with cascade showers, and sophisticated teak, stone, and leather accents. Guests can also look forward to updated dining experiences — like lunch spot La Pointe, which grills fresh-caught seafood over firewood and coconut embers, or open-air restaurant La Terrasse, which offers Mauritian specialties. Unchanged at Le Saint Géran is its aura of exclusivity, thanks to the resort’s unique position on a private peninsula jutting out from the island’s eastern shore. —Melanie Lieberman
